Application filed January 13, 1915. Serial No. 1,938.

To all whom t may concern Be it known that we, EDWmT T. PETERS,-

DnvID B. HOWARD, and JOI-IN M. MURRAY, citizens of the United States,the said EDWIN T. PETERS and DAVID B. HOWARD residing at Lincoln, inthecounty of Lancaster and State of Nebraska, and the said JOI-IN VI.MURRAY residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inl/Vindow-Sash Holders; and We do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to windows having sliding sash, and has for itsobject to provide an improved sash holder adapted for use as asubstitute for the ordinary weights and cords.

Generally stated, the invention consists of the novel devices andcombinations of devices hereinafter described and delined in the claims.

In the accompanying drawings which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings: Figure l is a view in elevation with someparts broken away and some parts sectioned, looking at the inner face ofa window frame and its sash; Fig. 2 is a vertical section taken on theline m2 m2 on Fig. l; Fig. 3 is a vertical section taken approximatelyon the line x3 m3 on Fig. 2, some parts being shown in full; Fig. 4 isan enlarged horizontal section taken approximately on the line :v4 00 onFig. l, some parts being shown in full; Fig. 5 is a horizontal sectiontaken on the line x5 :125 on Fig. 1; and Fig. G is avdetail in sectionon the line :c6 als on Fig..5.

The window frame 1 may be of any suitable construction, but need nothave the Weight boxes Which are ordinarily provided for windows whereinweights are employed.

The numerals 2 and 3 indicate, respectively, the upper and lower.slidingv sash which, except as hereinafter noted, are of the usualconstruction, and are confined for vertical sliding movements inthe'frame 1, by means of ordinary inside, outside and intermediate guidestrips 4, 5 and 6,-respec tively.

In accordance with our invention, the

sash 2 and 3, in their vertical edges, are formed with channels 7 thatincrease in depth toward the bottom of the said sash. The channels 7 ofthe lower sash extend completely from the bottom to the top thereof,while the channels 7 of the upper sash extend completely to the top, butpreferably terminate slightly short of the bottom thereof, (seeparticularly Fig. 2).

Arranged to run in the channels 7 and to press tightly against thebottoms thereof are anti-friction presser wheels 8 mounted on the endsof the prongs 9, which latter work in tubular sockets 10, and havesquare shanks 11 that work through square perforations in the extremeends of the said sockets. These square Shanks hold the rollers 8 in truealinement with the channels 7 and prevent rotation of the plungerswithin the sockets. The said sockets, at their open ends, are providedwith vertically bent flanges 12 that are set in flush with the innerfaces ofthe upright portions of the window frame 1 and are rigidlysecured thereto, preferably 'by screws. Coiled springs 13 which surroundthe stems 11 and are compressed between the ends or bottoms of the saidsockets 10 and the shouldered portions of the prongs 9,.

yieldingly, but quite tightly press the wheels 8 against the bottom ofthe respective channels 7.

As is evident, the yieldingly pressed wheels 8, acting against theupwardly diverging bottom surfaces of the opposite channels 7, not onlytend to hold the respective sash against vertical downward movements,but have a tendency to cause the same to rise. This tendency to rise,however, is not,.in itself, suflicient to actually raise the sash, butit makes the upward sliding Inovement of the sash an easy matter. In thebottoms of the channels in which the upper sash works, are stop blocks14 preferably secured in position by screws, and in the upperextremities of the `channels in which the lower sash Works, are similarstop blocks 15 operating upper presser wheels 8, and the Y upper stopblocks 15 prevent the lower sash from being moved upward above thecooperating lower presser wheels 8. When, however, the said stop blocksare removed,

which may be easily done, the upper sash may be moved downward below thecoperating rollers 8, and the lower sash may be moved upward abovetheir*Y cooperating rollers 8, so that when the outer and inner stopstrips 4, respectively, are removed, the said sash may be easily takenout of the window frame.

These improved sash holding devices, socalled, may be applied either tonew or to already built in windows, at small cost. In fact, they may beapplied at a less cost than the ordinary weights and cords, andfurthermore, make unnecessary the weight receiving boX structures of theframes, and thus eifect a further saving in the cost of newconstruction.

What we claim is:

The combination with a window frame and a sash mounted to slidevertically therein, said sash having in its opposite edges channels, thebottoms of which diverge upwardly, of sockets set into the sides of saidEDWIN T. PETERS. DAVID B. HOWARD. JOHN M. MURRAY.
